Title: A head lamp or light for vehicles, especially for motor vehicles
Inventor: DRESSLER HELMUT
IPC: F21V31/03
Filed: 1982-11-01
Abstract: An over pressure valve and a negative pressure valve are arranged in a cap of a semi-sealed head lamp both valves opening alternatively on the occurrence of comparatively low pressure differences between the interior (17) and the atmosphere (18). Each valve has a flexible valve portion (34), a central adhesive-free zone and an adjoining adhesive marginal zone along its longitudinal edges by which the valve is stuck to the cap (10) or to an annular base (29) stuck to the cap. On the occurrence of over pressure or negative pressure, the valve portion (34) moves and forms a connecting duct between the interior (17) and the atmosphere (18) (Figure 1). <IMAGE>
Patent GB-2108852-A (GB)
Title: Syringe
Inventor: MCKIE JOSEPH
IPC: A61M5/315
Filed: 1982-11-19
Abstract: The syringe of the invention has a barrel and an assembly of a plunger slidable in the barrel and an operating handle for the plunger and is characterized by incorporating a coupling between the two elements of the assembly in which spring fingers presented by one element of the assembly are engageable with an annular groove presented by the other element of the assembly. In operation, when the plunger is fully within the barrel the fingers engage the groove and the handle is coupled to the plunger. If the handle is pulled so far back that the plunger begins to leave the barrel the fingers spring apart out of the groove and the plunger and the handle become disconnected. <IMAGE>

Title: Methods and apparatus for use in arranging text
Inventor: LAMBOURNE ANDREW DAVID
IPC: G06F40/189
Filed: 1983-01-26
Abstract: Subtitling for example for television is time consuming because it is necessary to divide many subtitles into lines and for maximum intelligibility the ends of lines must be carefully selected. In addition for Teletext it is required to box each subtitle and to colour the text and background. Apparatus and method are described for entering subtitle next using a keyboard 10 into a computer 11 where the syntax and punctuation of the text is analysed and weights dependent thereon are inserted into a stored version of the text. The computer determines suitable ends for subtitle lines on the basis of the weighting and the effect of the position of possible line ends on the shape of the subtitle. Finally the subtitle is stored in an output buffer of the computer together with characters controlling the beginning and end of each line, its colours and position and then the contents of the buffer are recorded or transmitted if 'live'. <IMAGE>

Title: Method and apparatus for sewing slide fasteners to pairs of fabric pieces
Inventor: BOSER RONALD J
IPC: A44B19/42
Filed: 1986-03-04
Abstract: A slide fastener (1) is sewn to a pair of fabric pieces (2, 2) in a sewing station (5) defined by a double-needle sewing machine (4) with a pair of fastener stringers (32, 33) twisted around in mirror symmetry with respect to the longitudinal centerline of the slide fastener.

Patent GB-2181365-A (GB)
Title: Cleaning an air filter
Inventor: MORGAN CHRISTOPHER JAMES
IPC: B01D46/54
Filed: 1986-09-22
Abstract: A hydrophobic HEPA air filter partially blocked by small ferric oxide and iron particles, such as arise from the plasma arc cutting of iron or steel, is unblocked by subjecting the filter to a flow of a vapour (which term includes droplets), atomised liquid or solution, aerosol or the like, of such concentration and duration as not to block the filter but to dissolve the oxide, which is redistributed to leave gas-conducting voids when the liquid subsequently dries out. The vapour may be a cold water fog produced by solid carbon dioxide and hot water, or an acid or organic solvent may be used. The unblocked filter may be coated with silane-coated glass spheres to facilitate subsequent filtration. A particular application involves plasma cutting of equipment contaminated with plutonium.
Patent GB-2192995-A (GB)
Title: Well casing potential measurement amplifier
Inventor: GARD MICHAEL F
IPC: E21B47/00
Filed: 1987-07-20
Abstract: A well casing potential measuring tool including an improved first stage amplifier for precise amplification of small DC voltages between first and second points 18,20 on the well casing. A differential amplifier 28 has its inputs 30,32 coupled to the pair of voltage sensing electrodes, 18,20 by switching arrangement for alternately reversing the polarity of the connection of the input voltages to the differential amplifier. A unity gain inverter has its input connected to the differential amplifier output. In similar fashion a switching network alternately connects the output of the differential amplifier directly and via the output of inverter 36 to the input of a low-pass filter 46. A clock 50 drives the switches synchronously. As a result, the low-pass filter removes that portion of the signal which results from amplified offset voltages in the differential amplifier. The output of the low-pass voltage contains essentially only the desired amplified voltage signal. In an alternative embodiment (Fig. 4) in which the potentials to be measured result from a correct being driven through the casing, the direction of the driven current is alternately reversed to reverse the input to the differential amplifier. <IMAGE>

Title: Foldable baby carriage
Inventor: HAWKES PETER CHARLES
IPC: B62B9/26
Filed: 1987-10-05
Abstract: The frame 2 is braced in an erected position and can be "broken" and collapsed by pivoting in a fore and aft direction to fold the carriage frame means down on itself for transport or stowage. To achieve this action, a hook means 3 on a member 4 connected to a front frame 5 is held by a spigot 6 of a pivoted lever 7. A strut 8 extends from a rear frame part 9, a spigot 10 on the member 4 projecting through a slot 11 in a slidable sleeve 12 of the strut. To collapse the frame, the lever 7 is moved (arrow "A") to release the hook 3, the slide 12 is pulled up (arrow "B") and the handle 13 is pushed in the direction of arrow "C". The member 4 thus moves rearwardly, drawing the frame part 5 with it, to a position where the front and rear wheels 14, 15 are adjacent. To erect the frame, the handle is moved in direction "D" so that the hook 3 is engaged by spigot 6. A device to prevent swivelling of a bogie bearing the front wheels of the carriage is also disclosed, and comprises a stirrup 19 which may be moved from the inoperative position shown, by upward movement of part 24, to a locked position in which a detent on stirrup 19 engages a notch in wheel bearing 22, thus locking a wheel which would be secured on spigot 23 from movement. <IMAGE>
